Constrained optimization problems are with great difficulties to be solved for the complex influences of their constraints. However, many crossover operators in the constrained evolutionary algorithms have a disadvantage on bias search of the boundary. A novel uniform design based crossover operator coupled with a new space searching strategy aiming to overcome this disadvantage are proposed in this...
We proposed a new evolutionary algorithm for multiobjective optimization problems. The influence of constraints on search space and Pareto front are analyzed first. According to the analysis, a new clustering method based on domination is proposed, in which the infeasible solutions are employed. Then, aiming to converge to Pareto fronts of the multiobjective problems quickly, a differential evolution...
Evolutionary Testing has been shown a promising technology for the automatic test data generation. It reformulates test data generation as a metaheuristic search. A well- designed fitness function is essential to the efficiency of evolutionary search. Many efforts have been directed at the design and implementation of fitness function in recent years. However, previous work has just focused on the...
